Abstract: Disclosed is wristband and wrist wearable device, including: a wristband body portion, one end is connected to one end of a device body of a wrist wearable device, and the other end is a free end; and a memory metal portion, which is arranged on the wristband body portion and has an arc-shaped memory state in a natural state, so that the wristband body portion is naturally maintained in an arc shape. The memory metal portion comprises a strip-shaped memory metal piece including a first metal segment, a second metal segment, and a third metal segment that are sequentially connected, the first metal segment and the third metal segment extend along a length direction of the wristband body portion in parallel, the second metal segment is arranged at the free end of the wristband body portion and is provided with at least one bent portion.

Abstract: A dairy farm system comprises a plurality of apparatuses (11a-e) for performing actions related to the operation of the dairy farm system, wherein the apparatuses are connected in a network (12), and at least one of the apparatuses (21, 26-28) is movable. The movable apparatus is wirelessly connectable to the network via a short-range radio link (23a-c, 26a-c, 27a-c, 28a-c), preferably a Bluetooth link. Advantageously, the movable apparatus is kept continuously connected in the network (12) via the radio link during operation. In one embodiment the movable apparatus is a feed device (21), wherein feeding instructions are received, and feeding status or error information is sent, by the feed device via the radio link.

Abstract: A motion sensor unit (11) is intended to be carried by a domestic animal. The motion sensor unit (11) operates in parallel to and independently of a conventional transponder unit (1). The motion sensor unit (11) contains a motion detector (14) for measuring the activity of the animal by providing electrical pulses when the animal moves. Each hour is subdivided in a number of intervals in each one of which it is determined if the activity has exceeded a certain threshold. If it is the case, a count value is incremented. The count value is then transmitted once each hour and in addition also the count values of all the 23 previous hours. By transmitting repeatedly such information a good safety is obtained in the reception of the information signal, and this information can be used for complicated evaluation processing in a processor (7) or a supplementary personal computer (9).
